Quick Installation

Previous considerations:

Python 3.9 installed
Pip installed (comes with Python 3, no worries)
Virtualenv installed (comes with Python 3, no worries)
Python added to your local variables
If you have python 3.11 or other versions, it's necessary to configure a new environment because the default environment with which this project runs works under Python 3.9.
To configure a new environment with your Python version, do this:
- Delete the env folder on the root of this project
- Create a new env: python -m venv env
Note: It's known that the package psycopg2-binary==2.9.5 is compatible with python 3.11 version and psycopg2-binary==2.9.3 (used in this project) is compatible with python 3.9 If you have python 3.11, be careful to make this change in the requirements.txt (meaning change to psycopg2-binary==2.9.5 as we use Python 3.9 that works with psycopg2 2.9.3)

This project uses PostgreSQL as database (like described in step 52), so you will need to follow that step to download and configure your database if you want to use PostgreSQL. But, if you just want to use the default sqlite3 database that comes with django and run the project as quick as possible. Follow these steps :)

Clone the repository to your local folder
Open the folder repo with VS code or git bash

In VS terminal or git bash, input the following commands

 env/Scripts/activate #for vscode  # for git bash: source env/Scripts/activate
 pip install -r requirements.txt # don't forget to change here to psycopg2-binary==2.9.5 if you use python 3.11

Comment out the postgresql database config under crm/settings.py, so that you can switch to sqlite3, and change it to the default sqlite3

 # DATABASES = {
     # 'default': {
 	# 'ENGINE': 'django.db.backends.postgresql_psycopg2',
 	# 'NAME': env("DB_NAME"),
 	# 'USER': env("DB_USER"),
 	# 'PASSWORD': env("DB_PASSWORD"),
 	# 'HOST': env("DB_HOST"),
 	# 'PORT': env("DB_PORT"),
     # }
 # }

 DATABASES = {
     'default': {
 	'ENGINE': 'django.db.backends.sqlite3',
 	'NAME': BASE_DIR / 'db.sqlite3',
     }
 }

Continue the setup in the terminal, we are about to set this thing up :D

 python manage.py collectstatic
 python manage.py makemigrations
 python manage.py migrate
 python manage.py createsuperuser #create a user and assign a password as you like
 python manage.py runserver #add a port if the django default port (8000) is in use by other apps on your machine

Learn how to use below ...

How to use

Navigate to the home page http://192.168.0.127:8000/ and login with the superuser you created, add leads and agents as you want in http://192.168.0.127:8000/admin or create your agent acc in the home page.

Comprehensive guide to progressively implement this project

The pictures portray the results reached on every step and the versions keep track of the project's progress

1 Create & activate the virtual enviroment

In MINGW

 python -m venv enviroment
 source env/Scripts/activate

In VSCODE

 python -m venv enviroment
 env/Scripts/activate

2 Check packages

pip freeze

3 Install django

pip install django==3.1.4
pip freeze > requirements.txt

4 Create the project

django-admin startproject crm .

5 Add the gitignore

Create the gitignire file and fill with: https://github.com/github/gitignore/blob/main/Pythongitignore

6 Run the server

python manage.py runserver # port if necessary

7 Run migrate

python manage.py migrate

8 Create the app (for users/leads/payments)

python manage.py startapp leads

9 Add the new app 'leads' into the settings of the project

In crm/setting.py, edit

 INSTALLED_APPS = [
     'django.contrib.admin',
     'django.contrib.auth',
     'django.contrib.contenttypes',
     'django.contrib.sessions',
     'django.contrib.messages',
     'django.contrib.staticfiles',
     'leads'
 ]

10 Open models, edit & run

In leads/models.py, create the model Lead as a class

 class Lead(models.Model):
     first_name = models.CharField(max_length=20)
     last_name = models.CharField(max_length=20)
     age = models.IntegerField(default=0)

In the terminal

 python manage.py makemigrations  # create the 001_initial.py, auth_user is created, db.sqlite3 needs to be deleted in custom user
 python manage.py migrate	 # create the database/applying leads.0001_initial

In VS CODE install SQLite to see the database

11 Create a model Agent (every Lead will have an agent)

In leads/models.py

 class Agent(models.Model):
     user = models.OneToOneField(User, on_delete=models.CASCADE)

12 Add a customizable User model

In leads/models.py

 from django.contrib.auth.models import AbstractUser
 
 class User(AbstractUser)L
 	pass

In crm/settings.py
```
 AUTH_USER_MODEL = "leads.User"
```

Delete 001_initial.py and db.sqlite3 files

 python manage.py makemigrations
 python manage.py migrate

13 Models Managers

Check the leads in the python shell

 python manage.py shell

 from leads.models import Lead
 Lead.objects.all()

Output: <QuerySet []>

Creating a superuser
```
 python manage.py createsuperuser
```

Check the user, in the terminal python manage.py shell

 from django.contrib.auth import get_user_model
 User = get_user_model()
 User.objects.all()

Output: <QuerySet [<User: jose>]>

 from leads.models import Agent
 admin_user = User.objects.get(username="jose")
 admin_user

Output: <User: jose>

 agent = Agent.objects.create(user=admin_user)
 exit()

14 Configure the Agent to show up the email

Edit leads/models.py

 class Agent(models.Model):
 	user = models.OneToOnefield(User, on_delete=models.CASCADE)

 	def __str__(self):
 		return self.user.email

In ther terminal python manage.py shell

 from leads.models import Agent
 Agent.objects.all()

Output: <Queryset [<Agent: jose@mail.com>]>

 from leads.models import Lead
 jose_agent = Agent.objects.get(user__email="jose@mail.com")
 jose_agent

Output: <Agent: jose@mail.com>

 Lead.objects.create(first_name="Joe", last_name="Soap", age=35, agent=jose_agent)

Output: <Lead: LEAD OBJECT (1)>

Edit leads/models/py

 class Lead(models.Model):
 	first_name = models.CharField(max_length=20)
     	last_name = models.CharField(max_length=20)
     	age = models.IntegerField(default=0)
 	
 	def __str__(self):
 		return f"{self.first_name} {self.last_name}"
 
 class Agent(models.Model):
 	user = models.OneToOneField(User, on_delete=models.CASCADE)	
 	def __str__(self):
 		return self.user.email

In the terminal

 python manage.py shell
 from lead.models import Lead
 Lead.objects.all()

Output: <QuerySet [<Lead: Joe Soap>]>

15 Forms and create view

Run the server and go to http://127.0.0.1/admin

Add the user to show up in the admin site, go to leads/admin.py

 from .models import User, Lead, Agent
 
 admin.site.register(User)
 admin.site.register(Lead)
 admin.site.register(Agent)

Check http://127.0.0.1/admin output:

 Leads
 Agents	+Add  Change
 Leads	+Add  Change
 Users	+Add  Change

Compiled in the branch of ver-1.1

Redirect to http://127.0.0.1:8000/leads/ after creating a user In leads/view.py

 from django.shortcuts import render, redirect
 :
 :
 agent = Agent.objects.first()
 	Lead.objects.create(
 		first_name=first_name,
 		last_name=last_name,
 		age=age,
 		agent=agent
 		)
 		return redirect("/leads")

22 Using Django ModelsForm

Edit leads/forms.py

 from django import forms
 from .models import Lead
 
 class LeadModelForm(forms.ModelForm):
 	class Meta:
 		model = Lead
 		fields = (
 			'first_name',
 			'last_name',
 			'age',
 			'agent',
 		)

Simplify using LeadModelForm: edit leads/views.py, change LeadForm -> LeadModelForm

 from .forms import LeadModelForm
 
 def lead_create(request):
 	form = LeadModelForm()
 	if request.method == "POST":
 		form = LeadModelForm(request.POST)
 		if form.is_valid():
 			form.save()
 			return redirect("/leads")
 	context = {
 		"form": form
 	}
 	return render(request, "leads/lead_create.html", context)

Edit leads/lead_detail.html

 <body>
 	<a href="/leads">  Go back to leads</a>
 	<hr />
 	<h1>This is the details of {{ lead.first_name }}</h1>
 	<p>This persons age: {{ lead.age }} </p>
 	<p>The agent responsible for this lead is : {{ lead.agent }}</p>
 </body>

Test 21-3: Go to http://127.0.0.1:8000/leads/

23 Create the lead_update model

In lead/views.py

 def lead_update(request, pk):
 	lead = Lead.objects.get(id=pk)
 	form = LeadForm()
 	if reques.method == "POST":
 		form = LeadForm(request.POST)
 		if form.is_valid():
 			first_name = form.cleaned_data['first_name']
 			last_name = form.cleaned_data['last_name']
 			age = form.cleaned_data['age']
 			lead.first_name = first_name
 			lead.last_name = last_name
 			lead.age = age
 			lead.save()
 			return redirect("/leads")
 	context = {
 		"form": form,
 		"lead": lead
 	}
 	return render(request, "leads/lead_update.html", context)
 	```

Edit leads/urls.py

 from .views import lead_list, lead_detail, lead_create, lead_update
 app_name = "leads"
 
 urlpatterns = [
 	path('', lead_list),
 	path('<int:pk>/', lead_detail),
 	path('<int:pk>/update/', lead_update),
 	path('create'/, lead_create)
 	]
 	```

Create the templates/leads/lead_update.html file

 <!DOCTYPE html>
 <html lang="en">
 <head>
 	<meta charset="UTF-8">
 	<meta name="viewport" content="width=device-width, initial-scale=1.0">
 	<title>Document</title>
 </head>

 	<a href="/lead">Go back to leads</a>
 	<hr />
 	<h1>Update lead: {{ lead.first_name }} {{ lead.last_name }}</h1>
 	<form method="post">
 		{% csrf_token %}
 		{{ form.as_p }}
 		<button type="submit">Submit</button>
 	</form>
 </body>
 </html>

Simplify the lead_update model with LeadModelform in templates/leads/views.py

 def lead_update(request, pk):
 	lead = Lead.objects.get(id=pk)
 	form = LeadModelForm(instance=lead)
 	if request.method == "POST":
 		form = LeadModelForm(request.POST, instance=lead)
 		if form.is_valid():
 			form.save()
 			return redirect("/leads")
 	context = {
 		"form": form,
 		"lead": lead
 	}
 	return render(request, "leads/lead_update.html", context)

Test 23.1 Go to http://127.0.0.1:8000/leads/1/update/ and update/edit

24 Create the model delete

In lead/views.py, create the lead_delete model

 def lead_delete(request, pk):
     lead = Lead.objects.get(id=pk)
     lead.delete()
     return redirect("/leads")

Edit the leads/urls.py

 from .views import lead_list, lead_detail, lead_create, lead_update, lead_delete
 app_name = "lead"
 
 urlpatterns = [
 	path('', lead_list),
 	path('<int:pk>', lead_detail),
 	path('<int:pk>/update/', lead_update),
 	path('<int:pk>/delete/', lead_delete),
 	path('create/', lead_create)
 ]

Add a delete and update button the lead_detail.html page

 <body>
 	<a href="/leads">  Go back to leads</a>
 	<hr />
 	<h1>This is the details of {{ lead.first_name }}</h1>
 	<p>This persons age: {{ lead.age }} </p>
 	<p>The agent responsible for this lead is : {{ lead.agent }}</p>
 	<hr />
 	<a href="/leads/{{ lead.pk }}/update/">Update</a>
 	<a href="/leads/{{ lead.pk }}/delete/">Delete</a>
 </body>

Test 24.1 Go to http://127.0.0.1:8000/leads/, choose a lead to be deleted

25 Change URLs' names

Edit the leads/urls.py

 :
 urlpatterns = [
 	path('', lead_list, name='lead-list'),
 	path('<int:pk>/', lead_detail, name='lead-detail'),
 	path('<int:pk>/update/', lead_update, name='lead-update'),
 	path('<int:pk>/delete/', lead_delete, name='lead-delete'),
 	path('create/', lead_create, name='lead-create') #i.e. path('create-a-lead/', lead_create, name='lead-create')

Create the own userform: CustomUserCreationForm in leads/forms.py

from django import forms
from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm, UsernameField
from .models import Lead

User = get_user_model()

class CustomUserCreationForm(UserCreationForm):
    class Meta:
        model = User
        fields = ("username",)
        field_classes = {'username': UsernameField}

Edit the leads/views.py

#from django.contrib.auth.forms import UserCreationForm
from .forms import LeadForm, LeadModelForm, CustomUserCreationForm

class SignupView(CreateView):
    template_name = "registration/signup.html"
    form_class = CustomUserCreationForm

    def get_success_url(self):
        return reverse("login")

Test: Go to http://127.0.0.1:8000/signup/ and create a new user, verify the user in http://127.0.0.1:8000/login/

32 Test django

The test python files always start with the string "test_name.py"

Test the landing page, edit leads/templatees/leads/tests.py

from django.test import TestCase
from django.shortcuts import reverse

class LandingPageTest(TestCase):
    def test_status_code(self):
        # TODO some sort of test
        response = self.client.get(reverse("landing-page"))
        print(response.content)
        self.asserEqual(response.status_code, 200) #check status
        self.asserTemplateUser(response, "landing.html") #check response of page
    def test_template_name(self):
        response = self.client.get(reverse("landing-page"))
        self.assertTemplateUsed(response, "landing.html")
     def test_get(self):
        # TODO some sort of test
        response = self.client.get(reverse("landing-page"))
        self.asserEqual(response.status_code, 200)
        self.asserTemplateUser(response, "landing.html")

Test in console: python manage.py test

Create a tests folder in crm/leads, to run the tests' files {test_views,test_forms), also add the init.py

from django.test import TestCase
from django.shortcuts import reverse

class LandingPageTest(TestCase):
     def test_get(self):
        response = self.client.get(reverse("landing-page"))
        self.asserEqual(response.status_code, 200)
        self.asserTemplateUser(response, "landing.html")

33 Authorization restriction

Restrict users to be only the leads they created

Edit leads/views.py, pass the LoginRequiredMixin to the models that require it

from django.contrib.auth.mixins import LoginRequiredMixin

class LeadListView(LoginRequiredMixin, ListView):
:
class LeadDetailView(LoginRequiredMixin, DetailView):
:
class LeadCreateView(LoginRequiredMixin, CreateView):
:
class LeadUpdateView(LoginRequiredMixin, UpdateView):
:
class LeadDeleteView(LoginRequiredMixin, DeleteView):
:

Go to http://127.0.0.1/leads and verify the restriction with the error (you must be logged out or in incognito mode)

Modify the redirection so it ca redirect to the login site, go to crm/settings.py
```
:
LOGIN_REDIRECT_URL = "/leads"
LOGIN_URL = "/login"
```

Create a model for the user so that the agent will inherit the userprofile properties in crm/leads/models.py

class UserProfile(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    def __str__(self):
        return self.user.username

class Agent(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    organization = models.ForeignKey(UserProfile, on_delete=models.CASCADE)
    def __str__(self):
        return self.user.email

Add the userprofile tab in the database of the admin website, edit leads/admin.py

from django.contrib import admin
from .models import User, Lead, Agent, UserProfile

admin.site.register(User)
admin.site.register(UserProfile)
admin.site.register(Lead)
admin.site.register(Agent)

To test, delete the crm/db.sqlite3 database, migrate and create again the superuser

python manage.py migrate
python manage.py createsuperuser
    user: jose
    password: 1
python manage.py makemigrations
1
2
python manage.py migrate
python manage.py runserver

Note: We wouldn't want to create a user profile for the new users because that process ought be automatic, so the triggering of events is handled by signals in Django

34 Using signals

Edit leads/models.py
```
from django.db.models.signals import post_save

def post_user_created_signal(sender, instance, created, **kwargs):
    print(instance, created) #created boolena T/F if the user was or not created

post_save.connect(post_user_created_signal, sender=User)
```
Test in http://127.0.0.1:8000/admin/leads/user/, select a user and then in his profile, click save

For instance the above script depicts a process when we push the save buttom of a user through the admin site, after clicking the save command, the event post_user_created_signal is triggered and shows the name of the user(instance) in the VS terminal

Configure the creation of a userprofile after the user was created, in leads/models.py

def post_user_created_signal(sender, instance, created, **kwargs):
    if created:
        UserProfile.objects.create(user=instance)
    :

35 Create the Agents app

Create the new app in crm folder:
python manage.py startapp agents

Add the agent app in crm/settings.py

INSTALLED_APPS = [
    :
    'leads',
    'agents'
]

Create crm/agents/urls.py and edit

from django.urls import path
from .views import AgentListView, AgentCreateView

app_name = 'agents'
urlpatterns = [
    path('', AgentListView.as_view(), name='agent-list'),
    path('create/', AgentCreateView.as_view(), name='agent-create')
]

Add the app in crm/urls.py

:
urlpatterns = [
    :
    path('agents/', include('agents.urls', namespace='agents')),
    :
]

Edit the agents/views.py file

from django.views import generic
from django.contrib.auth.mixins import LoginRequiredMixin
from leads.models import Agent
from django.shortcuts import reverse
from .forms import AgentModelForm

class AgentListView(LoginRequiredMixin, generic.ListView):
    template_name = "agents/agent_list.html"
    def get_queryset(self):
        return Agent.objects.all()

class AgentCreateView(LoginRequiredMixin, generic.CreateView):
    template_name = "agents/agent_create.html"
    form_class = AgentModelForm

    def get_success_url(self):
        return reverse("agents:agent-list")

    def form_valid(self, form):
        agent = form.save(commit=False)
        agent.organization = self.request.user.userprofile  #agents have a organiz property, Check leads/models.py
        agent.save() #agent is save in the organization
        return super(AgentCreateView, self).form_valid(form)

Create the templates folder inside the agents app (crm/agents/templates) and then the folder crm/agents/templates/agents.
Inside agents/templates/agents/ create the agent_list.html file and edit it

{% extends "base.html" %}
    {% block content %}

AgentDetailView, AgentUpdateView, AgentDeleteView) 

app_name = 'agents'

urlpatterns = [
    path('', AgentListView.as_view(), name='agent-list'),

Test: Go to http://127.0.0.1:8000/agents and create/delete/update an agent, check ver-1.5

37 Filter the agents display only to their users counterparts

Edit the agents/views.py file
```
:
class AgentListView(LoginRequiredMixin, generic.ListView):
    template_name = "agents/agent_list.html"

    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization) #Changed this return Agent.objects.all()
```
Test - Correctly filtering agents for the users: Go to http://127.0.0.1:8000/admin/leads/agent and add an AGENT (there must be two users already created under different categories: organization and without orgnization or simply users)
Assign to the Agent:
User: Test1
Organization: Test2
Now login to another user, like Jose, check in http://127.0.0.1:8000/agents, you should only see your agent(s), not the ones recently assigned to different users or organizations!

Extend the filtering functionality where there is a queryset (where something is retrieved back to the client), in agents/views.py

from django.views import generic
from django.contrib.auth.mixins import LoginRequiredMixin
from leads.models import Agent
from django.shortcuts import reverse
from .forms import AgentModelForm

class AgentListView(LoginRequiredMixin, generic.ListView):
    template_name = "agents/agent_list.html"
    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization)

class AgentCreateView(LoginRequiredMixin, generic.CreateView):
    template_name = "agents/agent_create.html"
    form_class = AgentModelForm

    def get_success_url(self):
        return reverse("agents:agent-list")

    def form_valid(self, form):
        agent = form.save(commit=False)
        agent.organization = self.request.user.userprofile  #agents have a organiz property, Check leads/models.py
        agent.save() #agent is save in the organization
        return super(AgentcreateView, self).form_valid(form)

class AgentDetailView(LoginRequiredMixin, generic.DetailView):
    template_name = "agents/agent_detail.html"
    context_object_name = "agent"
    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization)

class AgentUpdateView(LoginRequiredMixin, generic.UpdateView):
    template_name = "agents/agent_update.html"
    form_class = AgentModelForm

    def get_success_url(self):
        return reverse("agents:agent-list")

    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization)

class AgentDeleteView(LoginRequiredMixin, generic.DeleteView):
    template_name = "agents/agent_delete.html"
    context_object_name = "agent"

    def get_success_url(self):
        return reverse("agents:agent-list")

    #here is even more important because we don't users to delete agents that belong to other users
    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization)

38 Create 2 type of users: agents & organizers

Create the type of users in crm/leads/models.py
```
from django.db import models
from djangodb.models.signals import post_save
from django.contrib.auth.models import AbstractUser

class User(AbstractUser):
    is_organizer = models.BooleanField(default=True)
    is_agent = models.BooleanField(default=False)
```
```
python manage.py makemigrations
python manage.py migrate
python manage.py runserver
```
Verify: Go to http://127.0.0.1:8000/admin/leads/user/ choose a user and check the options down below for organizer(set to True as default) and agent.

Only users set to be organizers can create and see all agents available
Users which are agents can only see the agent which is assigned to them.
Sometimes there might be an error in makemigrations, so either delete the database: dbsqlite3, or delete the init files: 0001_initial.py, etc.

39 Render the tabs that agents/organizer should only see

>In this case, organizers can see the correct left tabs: Agents & Leads, and agents can see only Leads<br>

Edit the registration/navbar.html file

:
{% if not request.user.is_authenticated %}
    <a href="{% url 'signup' %}" class="mr-5 hover:text-gra-900">Signup</a>
{% else %}
    {% if request.user.is_organizer %}
        <a href="{% url 'agents:agent-list' %}" class="mr-5 hover:text-gra-900">Agents</a>
    {% endif %}
    <a href="{% url 'leads:lead-list' %}" class="mr-5 hover:text-gra-900">Leads</a>
{% endif %}
<!--
{% if not request.user.is_authenticated %}
    <a href="{% url 'signup' %}" class="mr-5 hover:text-gra-900">Signup</a>
{% else %}
    <a href="{% url 'agents:agent-list' %}" class="mr-5 hover:text-gra-900">Agents</a>
    <a href="{% url 'leads:lead-list' %}" class="mr-5 hover:text-gra-900">Leadss</a>
{% endif %}
-->
:

Test: create two users and configure one to is_organizer, the other to be is_agent (name this user as agent to be distringuishable).
Now procees to login with the agent user and verify that there is no agent tab in the right side of navbar.

Restrict agents to hardcorde the url http://127.0.0.1:8000/agents, create the agents/templates/mixins.py to restrict to login and restrict see other agents if is not a organizer

from django.contrib.auth.mixins import AccessMixin
from django.shortcuts import redirect

class OrganizerAndLoginRequiredMixin(AccessMixin):
    """Verifiy that the current user is authenticated and is an organizer"""
    def dispatch(self, request, *args, **kwargs):
        if not request.user.is_authenticated or not request.user.is_organizer:
            return redirect("leads:lead-list")
        return super().dispatch(request, *args, **kwargs)

Import the custom mixins: OrganizerAndLoginRequiredMixin (custom restriction for login and view of other agents) in agents/views.py

from django.views import generic

from django.shortcuts import reverse

        agent.organization = self.request.user.userprofile  #agents have a organiz property, Check leads/models.py
        agent.save() #agent is save in the organization
        return super(AgentcreateView, self).form_valid(form)

class AgentDetailView(LOrganizerAndLoginRequiredMixin, generic.DetailView):
    template_name = "agents/agent_detail.html"
    context_object_name = "agent"
    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization)

    def get_queryset(self):
        organization = self.request.user.userprofile
        return Agent.objects.filter(organization=organization)

Restrict also in leads/views.py regarding leadcreateview,

:
from agents.mixins import OrganizerAndLoginRequiredMixin
:
class LeadCreateView(OrganizerAndLoginRequiredMixin, CreateView):
:
class LeadUpdateView(OrganizerAndLoginRequiredMixin, UpdateView):
:
class LeadDeleteView(OrganizerAndLoginRequiredMixin, DeleteView):

Show Create a new lead to only organizers in the templates/leads/lead_list.html

{% endif %}
<!--
<div>
	<a class="text-gray-500 hover:text-blue-500" href="{% url 'leads:lead-create' %}">Create a new lead</a>

-->
:

Test: Login as an agent user, go to http://127.0.0.1:8000/leads, check the tab if available, and hop over to ``http://127.0.0.1:8000/leads/create`, the sites should redirect to http://127.0.0.1:8000/leads/

40 Leads queryset

Showing the leads to be seen by the agents that they belong to
Initially when leads are created, they shouldnt have set up an agent, so their agent will be null.
Go to ./leads/models.py and edit

class Lead(models.Model):
    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)
    age = models.IntegerFiled(default=0)
    organization = models.ForeignKey(UserProfile, on_delete=models.CASCADE)# add the userprofile or organization that a Lead belongs
    agent = models.ForeignKey("Agent", null=True, blank=True, on_delete=models.SET_NULL) # so when the agent is deleted, the lead wont be deleted and will just remain an a lead without agent 

    def __str__(self):
        return f"{self.first_name} {self.last_name}"

python manage.py makemigrations
python manage.py migrate
1
exit
python manage.py runserver

Leads filtered by the user of the agent (matchs the user of the lead: self.reques.user)

Edit the leads/views.py to configure the leads querysets so we end up restricting the shown of the leads based on the assigned agents

from django.shortcuts import render, redirect, reverse

        queryset = Lead.objects.filter(organization = user.userprofile)
    else:
        queryset = Lead.objects.filter(organization=user.agent.organization)

41 Invite an agent

Modify agents/forms.py, so that when the agent is created, a user is immediately created as well.

from django import forms
from django.contrib.auth import get_user_model
from django.contrib.auth.forms import UserCreationForm

User = get_user_model()
class AgentModelForm(forms.ModelForm):
    class Meta:
        model = User
        fields = (
            'email',
            'username',
            'first_name',
            'last_name'
        )

Edit agents/views.py, to create an agent user

:
from django.core.mail import send_mail
:
class AgentCreateView(OrganizerAndLoginRequiredMixin, generic.CreateView):
		template_name = "agents/agent_create.html"
		form_class = AgentModelForm

		def get_success_url(self):
			return reverse("agents:agent-list")

		def form_valid(self, form):
			#create the user type agent
			user = form.save(commit=False)
			user.is_agent = True
			user.is_organizer = False
			user.save()
			# create the agent for that user
			Agent.objects.create(
				user=user,
				organization=self.request.user.userprofile
			)
			send_mail
				subject="You are invited to be an agent",
				message="You were added as an agent on CRM. Please come login to stat working.",
				from_email="admin@test.com"
				recipient_list=[user.email]
			return super(AgentCreateView, self).form_valid(form)

Test: Sign in like Jose and go to http://127.0.0.1:8000/agents/create, enter the details and submit, check the agent just created and the email on the terminal.
Also go to the admin website and check the user, it actually doesn't have a password so set it up like below, edit agents/views.py

import random
	class AgentCreateView(OrganizerAndLoginRequiredMixin, generic.CreateView):
		template_name = "agents/agent_create.html"
		form_class = AgentModelForm

		def get_success_url(self):
			return reverse("agents:agent-list")

		def form_valid(self, form):
			#create the user type agent
			user = form.save(commit=False)
			user.is_agent = True
			user.is_organizer = False
            user.set_password(f"{random.randint(0, 100000)}")  #ADDED, need to reset pass

Test 44.1: Assign a lead to an agent

45 Adding a feature to categorize via a model

In ./leads/models.py

class Lead(models.Model):
    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)
    age = models.IntegerFiled(default=0)
    organization = models.ForeignKey(UserProfile, on_delete=models.CASCADE)
    agent = models.ForeignKey("Agent", null=True, blank=True, on_delete=models.SET_NULL)
    category = models.ForeignKey("Category", null=True, blank=True, on_delete=models.SET_NULL)

    def __str__(self):
        return f"{self.first_name} {self.last_name}"

class Category(models.Model):
    name = models.CharField(max_length=30) #New, Contacted, Converted, Unconverted
    
    def __str__(self):
        return self.name

Modify the ./leads/admin.py

from django.contrib import admin
from .models import User, Lead, Agent. UserProfile, Category

admin.site.register(Category)
admin.site.register(User)
admin.site.register(UserProfile)
admin.site.register(Lead)
admin.site.register(Agent)

In the terminal:

python manage.py makemigrations
python manage.py migrate
python manage.py runserver

Test 1: Create the categories {Contacted, Converted, Unconverted} from the admin site in http://127.0.0.1:8000/admin/leads/category/add

46 View the list of categories

Edit ./leads/views.py

:
class CategoryListView(LoginRequiredMixin, generic.ListView):
    template_name = "leads/category_list.html"

Edit ./leads/models.py and migrate with null the default properties

:
class Category(models.Model):
    name = models.CharField(max_length=30) #New, Contacted, Converted, Unconverted
    organization = models.ForeignKey(UserProfile, null=True, blank=True, on_delete=models.CASCADE) #adding null and blank so that when the migration is made, the parameters don't require default values
    def __str__(self):
        return self.name

In the terminal run: python manage.py makemigrations and python manage.py migrate

Modify again crm/leads/models.py and migrate without null and blank
```
:
class Category(models.Model):
    name = models.CharField(max_length=30) #New, Contacted, Converted, Unconverted
    organization = models.ForeignKey(UserProfile, on_delete=models.CASCADE) #adding null and blank so that when the migration is made, the parameters don't require default values
    def __str__(self):
        return self.name
```
In the terminal run: python manage.py makemigrations and choose the option 2) Ignore for now..., then apply python manage.py migrate and despite the error run the server python manage.py runserver which yields an uapplied migration error. Go to http://127.0.0.1:8000/admin/leads/category/ and configure the organization of the categories, check Tes45.1 {Name: Contacted, Organization: jose, Name: Converted, Organization: jose, Name: Unconverted, Name: Jose}. Finally stop the server and migrate without problems python manage.py migrate and run the server

from .views import (LeadListView, ..., CategoryListView, CategoryDetailView)

urlpatterns = [
    :
    path('categories/<int:pk>/', CategoryDetailView.as_view(), name='category-detail'),
]
path

Update the ./leads/templates/leads/category_list.html (See line 3438)

{% for category in category_list %}
<tr>
    <td class="px-4 py-3">
        <a href="{% url 'leads:category-detail' category.pk %}"> {{ category.name }}</a>
    </td>
    <td class="px-4 py-3">TODO count</td>
</tr>
{% endfor %}

Configure ./leads/templates/leads/lead_list.html (line 8)

{% extends "base.html" %}
{% block content %}
<section class="text-gray-600 body-font">
    <div class="container px-5 py-24 mx-auto flex flex-wrap">
        <div class="w-full mb-6 py-6 flex justify-between items-center border-b border-gray-200">
            <div>
                <h1 class="text-4xl text-gray-800">Lead</h1>
                <a class="text-gray-500 hover:text-blue-500" href="{% url 'leads:category-list' %}">
                    Vuew categories
                </a>
            </div>
            {% if request.user.is_organizer %}
            <div>
                <a class="text-gray-500 hover:text-blue-500" href="{% url 'leads:lead-create' %}">Create a new lead</a>
            </div>
            {% endif %}
        </div>

Test: Go to http://127.0.0.1:8000/admin/leads/lead, choose a lead a configure his category (i.e. contacted)<br> Then go to http://127.0.0.1:8000/leads/, click on View categories and view the contacted in the Name column and verify that the user is listed there

Simplify the selection of leads in the category, in crm/leads/templates/leads/category_detail.html (line 28)

<tbody>
    {% for lead in category.leads.all %} <!-- {% for lead in leads %} -->
        <tr>
            <td class="px-4 py-3">{{ lead.first_name }}</td>
            <td class="px-4 py-3">{{ lead.last_name }}</td>
        </tr>
    {% endfor %}
</tbody>

And comment the following section of crm/leads.views.py

:
class CategoryDetailView(LoginRequiredMixin, DetailView):
    template_name = "leads/category_detail.html"
    context_object_name = "category"

    #def get_context_data(self, **kwargs):
    #    context = super(CategoryDetailView, self).get_context_data(**kwargs)
    #    leads self.get_object().leads.all()
    #
    #    context.update({
    #        "leads": leads
    #    })
    #    return context

50 Styling a little bit more

Go to leads/models.py and add {descrip, date, phone, email} to the model

class Lead(models.Model):
    first_name = models.CharField(max_length=20)
    last_name = models.CharField(max_length=20)
    age = models.IntegerFiled(default=0)
    organization = models.ForeignKey(UserProfile, on_delete=models.CASCADE)
    agent = models.ForeignKey("Agent", null=True, blank=True, on_delete=models.SET_NULL)
    category = models.ForeignKey("Category", related_name = "leads", null=True, blank=True, on_delete=models.SET_NULL)
    description = models.TextField()
    date_added = models.DateTimmeField(auto_now_add=True)
    phone_number = models.CharField(max_length=20)
    email = models.EmailField()
    :

In the terminal:

python manage.py makemigrations
Selection an otion: 1
>> timezone.now

Do for all the leads that were created and end with

python manage.py migrate
python manage.py runserver

Edit the leads/forms.py

class LeadModelForm(forms.ModelForm):
    class Meta:
        model = Lead
        fields = (
            'first_name',
            'last_name',
            'age',
            'agent',
            'description',
            'phone_number',
            'email',
        )

Then run again python manage.py runserver

Fix in ./leads/view.py/ 50 - 4:40 Error at creating a lead in http://127.0.0.1:8000/leads/create, after clicking on submit

def form_valid(self, form):
    lead = form.save(commit=False)
    lead.organization = self.request.user.userprofile
    lead.save()
    send_mail(
        subject="A lead has been created",
